PADLOCK.

SPECIFICATION forming part of Letters Patent No. 578,791, dated March16, 1897.

Application filed August 15, 1895. Serial No. 559,371. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM F. TROAST and JACOB B. AMWAKE,citizens ofthe United States, residing at Lancaster, county of Lancaster, State ofPennsylvania, have invented certain Improvements in Padlocks, of whichthe following is a specification.

This invention relates to improvements in that class of padlocks inwhich a shackle is formed by projecting a bolt across the mouth of abight in the case; and the invention consists in certain novel featuresof construction and combination of parts, whereby we obtain aneasy-working padlock of compact and simple construction, as will behereinafter fully described, and then pointed outin the claims.

Our invention is illustrated in the accompanying drawings,forming a partof this specification, and in which Figure l is a perspective view ofthe interior of the lock, the bolt and the operating mechanism beingshown in the position occupied thereby when said bolt is engaged with astaple; and Fig. 2, asimilarview, but showing the same parts in theposition occupied by them when the bolt is drawn back into the case.Fig. 3 is a perspective inner face view of the closing-plate; and Fig.4, a similar view of the case, the bolt and the actuating mechanismbeing removed. Fig. 5-is a perspective bottom view of the bolt andlocking mechanism detached from the case, showing the parts in theposition they occupy when the bolt is engaged with a staple; and Fig. 6,asimilar view of the same parts when in the position they occupy whenthe bolt is drawn back into the case. Fig. 7 is a bottom perspectiveview of the bolt-lever and bolt; and Fig. 8, a top plan view thereof, apart being cut away. Fig. 9 is a perspective view of the tumbler, andFig. 10 a similar view of a modified form thereof. Fig. 11 is a faceview of the key. Fig. 12 is a View of the side of the bight indicated byarrow 2.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings,A

case, the lower portion of which bight is surrounded by a rim a,the endswhereof are separated from the ends of rim a by openings 1) b.

A is a closing-plate,having perforations a adapted to engage rivet-pinsa a a formed with the body A a of the case, as is usual.

72 is a fulcrum-pin located below the center of rim a, and on pin 12 isfulcrumed aboltlever having arms B B.

B is a segmental bolt on the end of arm B and adapted to oscillate incontact with rim a through opening I). The boltformsashoulder b with armB adjacent to rim (1, and from the shoulder projects a horizontal stud bembraced by one end of a coiled spring S, that lies against rim a andhas its other end engaging a socket b in the base of rivet-pin aLever-arm B carries a segmental tongue D, that oscillates in contactwith rim (1 through the adjacent opening I). Tongue D also has ashoulder d, adapted to engage the base of the rivet-pin a on the side ofthe case, thereby limiting the backward movement of said tongue. TongueD has a horizontal groove d in its outer edge, wherein the inner end ofthe stem e of a latch is hinged on a pin d On the outer edge of head Eof the latch is a hook e, constructed to take over the adjacentextremity of rim. or when the tongue is en gaged with the opening 12,and on the lower portion of head E is a lip e adapted to be engaged by astaple (shown by broken lines V in Fig. 1) entering bight A to disengagehook e from rim (2. The hook e is actuated to engage the extremity ofrim a by a coiled spring S, having one end bearing on the bottom ofgroove d and the other end seated in a recess e in the inner edge ofstem 6, as seen in Fig. 8, and when said hook is released from rim aspring S projects bolt B across bight A into opening I), engaging thesame with staple V.

The bolt B and the tongue D extend below the lower face of bolt-lever BB and rest on segmental ribs a on the back plate of the case, wherebysaid lever'is raised above the back plate. Beneath the bolt-lever playsa lever, through which the same is actuated against the tension ofspring S. One end of stem F of the actuating-lever is pivoted on a studf, adjacent to the base of rivet-pin a ICO and on the other end is ahead F, having in its upper portion a curved slot f, engaged by apin onthe under side of arm B. In the lower portion of said head F is aT-slot, the stem f of which is on the side of the transverse part fthereof opposite slot f. This T-slot is engaged by a pin 9 on the underside of a tumbler G, as and for a purpose to be de scribed.

It will be observed that the part f of the T-slot is curved and that thestem f is not radial to said curved part f but is deflected, so as toallow said pin 9 to travel lengthwise thereof with the oscillatingmovement of the head F of the actuating-lever.

The tumbler G has a perforation g, through which it is engaged with afulcrum-pin 9 adjacent to the lower rivet-pin a Pin g projects abovetumbler G and is embraced by the loop of a spring H, one arm, h, ofwhich bears against rim (1, and the other, h, against a stud g on theouter face of tumbler G, whereby pin 9 of said tumbler is actuated toengage the inner end of part f of the T-slot and the tumbler is held inthe path of travel of the key.

L is a ward on the tumbler, constructed to be engaged by the bit K ofthe key K. The width of this ward is varied to adapt the tumbler to beactuated by different keys. This tumbler is actuated by the engagementof ward L with the bottom of the notch in the bit of the key.

.In a modified construction of tumbler shown in Fig. 10 the tumbler isactuated by the engagement of the key-bit with the sh o'ulder L, theward not being wide enough to reach the bottom of the notch in the key.The construction of these tumblers can be modified to any extent toadapt them to be actuated by keys of diiferent construction. The stud Lon the closing-plate serves to prevent the use of akey having a bitlonger than that required to open the lock or itself serves as a ward.

M is a slotted keyguide of the usual construction, having the endsrespectively journaled in the front and back plates of the lockcase.

On the inner face of the closing-plate are ribs a that bear on the leverB B and the parts connected therewith to assist in holding them in theirproper positions. The stud N forms, with depressed wall a a passage forlip e of the latch, as the head of the same passes through opening I),while the boss N bears on the inner end of spring S to secure the samein position in socket 19 as shown by broken lines 3, Fig. 2.

In operating, the parts being in the position shown in Figs. 1 and 5,the key turns the tumbler back until pin 9 registers with stem f of theT-slot, simultaneously with which the bit of the key engages and raiseshead F of the actuating-lever, which, through pin b elevates arm B,drawing bolt B back into the case and the head E of the latch into bightA until the hook e on said head takes over the adjacent end of rim (1,locking the boltin its retracted position. As the head F is raised pin 9travels down the stem of the T-slot. In inserting a staple into bight Ait is done so as to engage said staple with lip 6 whereby hook c isdisengaged from the end of rim a, when the tension of spring S projectsbolt B across bight A and restores the parts to the position previouslyoccupied. thereby. Should it be attempted to open the lock with a keyhaving a bit of greater depth than that of the true key, the tumblerwill be forced back until pin gpasses stem f of the T-slot before thebit engages the head F, whereby said pin will engage the outer end ofpart f of the T-slot and prevent any movement of the actuating-lever.

To do not confine ourselves to the details of construction herein shownand described, as it is. obvious that many changes may be made thereinwithout departing from the spirit and scope of our invention. It is notnecessary that the bolt and tongue operate contiguous to the edge wallof the case, though it is'preferable, nor is it necessary that the boltand tongue play through opposite openings in the sides of the bight;neither is it necessary that the actuating-lever and tumbler be arrangedas shown, but it is thought that such arrangement is the best with theconstruction of the parts indicated.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-
